[ABSTRAK
Pada laporan akhir tesis ini telah dikembangkan suatu sistem untuk magnetisasibahan magnet menjadi magnet permanen dan demagnetisasi denganmengurangi kuat medan magnet suatu magnet permanen. Sistem ini digunakanuntuk magnetisasi bahan magnet seperti Ferit, PrFeB, NdFeB dan jenisbahan magnet yang lain. Bahan magnet dapat dimagnetisasi menjadi magnetpermanen dengan menerapkan medan magnet sampai diatas titik saturasimagnet dari bahan magnet pada waktu singkat atau dikenal dengan impulsemagnetizer. Penerapan medan magnet menghasilkan momen magnetik danmemaksa domain-domain magnetik secara bertahap mengikuti arah medanmagnet yang diterapkan. Jika medan magnet eksternal lebih kuat dari medanmagnet saturasi magnetik dari bahan magnet maka domain-domain magnetikakan diorientasikan dengan arah yang baru. Sistem ini menggunakan kapasitoruntuk menyimpan muatan listrik dan kemudian diterapkan pada lilitankawat berbentuk solenoid multi lapis. Pada tesis ini telah berhasil melakukanmagnetisasi dan demagnetisasi bahan magnet Ferit, PrFeB dan NdFeB denganukuran bahan maksimal 26mm.
ABSTRACT
On this nal thesis report has been developed a system for the magnetizationof the magnetic material become permanent magnets and demagnetizationby reducing the magnetic eld strength of a permanent magnet. This systemis used for magnetize the magnetic material such as Ferrite, PrFeB, NdFeBmagnets and other types of magnetic materials. Magnetic material can bemagnetized into a permanent magnet by applying a magnetic eld above thesaturation point of the magnetic material in a short time, known as impulsemagnetizer. Application of a magnetic eld generates a magnetic moment anddomain-domain magnetic force gradually follow the direction of the appliedmagnetic eld. If the external magnetic eld is stronger than the magnetic eld of a magnetic saturation of the magnetic material, the magnetic domainswill be oriented to the new direction. This system uses a capacitor to storeelectrical charge and then applied to the multi-layer solenoid or coil by dischargingprocess. On this thesis has been successfully doing magnetizationand demagnetization magnetic materials such as Ferrite, NdFeB, PrFeB witha maximum material size of 26mm.;On this nal thesis report has been developed a system for the magnetizationof the magnetic material become permanent magnets and demagnetizationby reducing the magnetic eld strength of a permanent magnet.
